Abstract

An LED lamp comprises a lampshade and two LED modules, wherein the lampshade comprises a concave shell and a fixing plate, the top of the shell is provided with an opening, the fixing plate is accommodated in the shell, and the two LED modules are attached to both sides of the fixing plate and opposite to the inner wall of the shell at intervals. The two LED modules comprise a substrate and a plurality of LEDs. The substrate is attached to the fixing plate and the LEDs on both sides of the fixing plate are alternately arranged along the length direction of the fixing plate. At least part of the light sent out from two LED modules irradiates onto the inner wall of the housing, then irradiates to the outside of the opening through the reflection of the inner wall. The light from the LED modules simultaneously irradiates to the outside of the opening from a plurality of directions of the lamshade inside through the reflection of the inner surface of the lampshade, thereby forming a softer surface light source and avoiding glare phenomenon.

Fig. 2 is the three-dimensional exploded view of led lamp shown in Figure 1.
Fig. 3 is the attached view of led lamp shown in Figure 1.
Fig. 4 is along the sectional view of IV-IV line among Fig. 1.
Embodiment
Please refer to Fig. 1 and Fig. 2, be depicted as the led lamp 100 of a preferred embodiment of the present invention, this light fixture 100 comprises a lampshade 10, a fixed head 20 and two light emitting diode module 30, this lampshade 10 is the housing of an indent, and these two light emitting diode module 30 are installed in this lampshade 10 by this fixed head 20.
This lampshade 10 comprises a housing 11 and two end plates 13.This housing 11 extends along longitudinally, and its xsect is " U " shape, and promptly this housing 11 forms depression from the top to the bottom.This housing 11 has a U-shaped inwall 110.The bottom of this housing 11 is provided with two through holes 16.In other were implemented, this housing 11 also can be other concave shape, was " V " shape or trapezoidal lengthwise arch or the like such as semisphere, semielliptical shape, xsect.
These two end plates 13 are semicircular flat board, and these two end plates 13 one respectively are connected in vertical two ends of this housing 11, and this housing 11 surrounds with end plate 13 and forms a groove 15.This end plate 13 has an inwall 130, and the inwall 110 of this inwall 130 and housing 11 is relative with this groove 15.Top relative with through hole 16 on this lampshade 10 is provided with an opening 156, and this opening 156 makes this groove 15 communicate with the external world.The width of this groove 15 broadens gradually along the direction from the bottom of this lampshade 10 to the top.The surface of described inwall 110,130 is coated with the material with highly reflective, such as nickel plating or aluminize.
This fixed head 20 can be made with the material with better thermal conductivity, such as aluminium sheet or copper coin.This fixed head 20 is rectangular flat board.This fixed head 20 along with the direction that vertically parallels of housing 11, an end of this housing 11 extends to the other end certainly.This fixed head 20 comprises the vertical side 23 of two symmetries, and these two sides 23 are in order to install light emitting diode module 30.The bottom of this fixed head 20 also offers two fixed orifices 26 (referring to Fig. 4), and these two fixed orifices 26 are corresponding with the through hole 16 of housing 11.Screw 60 can be passed through hole 16 and locking in fixed orifice 26, thereby this fixed head 20 is installed in this lampshade 10 vertically.In other embodiments, this fixed head 20 also can be connected with these housing 11 one.
Please be simultaneously with reference to Fig. 3, each light emitting diode module 30 comprises a substrate 31 and some light emitting diodes 33.This substrate 31 extends along the direction parallel with fixed head 20, and short slightly than this fixed head 20.The longitudinally even compartment of terrain of these light emitting diodes 33 is installed on this substrate 31.This substrate 31 is provided with a layer printed circuit that is electrically connected with light emitting diode 33.Described substrate 31 is installed in respectively on the side 23 of fixed head 20 by welding, and, the light emitting diode 33 of both sides is interspersed along the length direction of fixed head 20, and the heat that so can disperse light emitting diode 33 to produce when work reaches better radiating effect.These light emitting diodes 33 are relative with the inwall 110 of described housing 11.These light emitting diodes 33 are divided into two rows, lay respectively at the left and right sides of this fixed head 20, and each row's light emitting diode 33 promptly is installed on the corresponding substrate 31, and this two rows light emitting diode 33 is mutually back to setting.
Please consult Fig. 4 simultaneously, this fixed head 20 is positioned at the central authorities of groove 15, and along the length direction setting of this lampshade 10, thereby this groove 15 is separated into symmetrical two parts.Each light emitting diode 33 has a light-emitting area 330, and this light-emitting area 330 is relative with the inwall 110 of this housing 11.The light that sends from this light-emitting area 330 and the inside surface of this lampshade 10 intersect.Such as, a part of light 71 that this light-emitting area 330 is sent at first shines on this inwall 110, shines to the direction of opening 156 by the reflection of inwall 110 then.Some light (figure does not show) shines to the direction of this opening 156 by the reflection of the inwall 130 of end plate 13.Particularly, in the present embodiment, the light that penetrates with maximum beam projecting angle from the edge of this light-emitting area 330 just intersects at the edge of this housing 11 or end plate 13, as light 73.
Generally speaking, the light of described light emitting diode 33 all can shine out from this opening 156 then earlier through the inside surface reflection of this lampshade 10.Therefore, human eye all can not directly be seen the light that these light emitting diodes 33 are sent from any angle in the outside of the opening 156 of this light fixture 100.By the inside surface reflection of lampshade 10, the light of light emitting diode 33 shines to the outside of this opening 156 simultaneously from a plurality of directions of the inboard of this lampshade 10, thereby forms comparatively soft area source, has avoided glare phenomenon.
In other embodiments, most of light of light emitting diode 33 need be through the reflection of the inside surface of lampshade 10, and part light can be not yet via the reflection of the inside surface of lampshade 10, and direct directive opening 156 also can be alleviated dazzle so largely and produce.
